PHOTOS: Sylvester Bridge Construction Progress Update
From BTB Contributor Brett Fish comes this photo montage showing the latest progress on the Sylvester Bridge construction:
“There will be approximately 89,000 feet of cable used to support the bridge structure – 22 cables of 7-strand, 230-feet long each,” Fish said.
With the bridge deck pour completed Dec. 21st, the next job is pushing cable through the length of the spans. A total of 16 tubes require 22 cables each, 230 feet long. Ten roll/bundles of cable will be installed in about 2 days.
The cables will then be tensioned making the bridge fully self supporting and causes the bridge to arc upwards about 2-3 inches. The metal construction support beams can then be extracted from underneath the spans.
Concurrently, the sidewalk and curb forms are being constructed. All the deck forms from underneath the spans have been removed.
